Chinese and Japanese religion, have a lot of history behind them. The three most formal traditions are Confucianism, Daoism, and Buddhism. These three things make up China's traditions. There are different cities in China that focus on these three traditions.
In Taiwan, Hong Kong, and Singapore people know all about these three traditions.
As stated in "World Religions", the traditions rely on two principles. One being the cosmos, which is the sacred place and all aspects of it. Confucianism is based on relationships between people and society. According to Confucius, the primary relationship is the relationship between a parent and a child, especially a father and a son.
The difference with Daoism is that it does not rely mainly on the bond between parent and their child. Daoism is more about how to gain order and harmony in ones life. Mainly finding yourself and finding out what you mean to yourself.
In China, Buddhist has founded schools. For example they founded "The Chinese Buddhist School of Chan". Buddhism emphasizes rituals and religious practices are relevant to life in the world. Buddhism has no caste system, but is known as a worldwide religion. Not only is Buddhism a popular religion in China, but as well in the Unites States of America, Canada, Tibet, and also Japan. In the United States of America, Buddhist came to North America by way of Chinese and Japanese immigrants. In China, Buddhism encounters Confucianism and Taoism.
Japan encounters Buddhism differently. Japanese encounter Shinto, which stresses veneration of Kami, divine forces in nature. Buddhism in Japan is a world religion that commands the devotion of millions of people throughout Asia. The roots of Shinto are a major part of Japanese prehistory. In the middle of the sixth century, writing was not available in Japanese writing only in Chinese writing. The thing about Chinese and Japanese writing is that to me it all looks the same.
